SYNOPSIS

A key is given to the Indo-Australasian species of Pectiniseta Stein. Descriptions are given of the type-species, pectinata (Stein), and of the four Australian species, australis (Malloch), new comb., occulta sp. nov., similis sp. novo and torresiana sp. novo Notes are given on the other two Australasian species. A catalogue of the described species in the genus is given.

INTRODUCTION

The genus Pectiniseta was described by Stein (1919: 145) for a species 0 with an unusual head-profile, where a sharp angle is formed at the profrons, with a long face and long antennae, and with a pectinate arista in the male sex. The genus has been maintained in subsequent revisionary work by Malloch (I 929b), Crosskey (1962) and Snyder (1965), and these authors, particularly Malloch and Crosskey, have emphasized the very close relationship betwe~n Pectiniseta and Lispocephala Pokorny. The characters of the pectinate male arista and the long-plumose female arista, combined with the angular head-profile (figs 1 and 2), are still the principal characters that have been used to define the genus and to differentiate it from Lispocephala.

In a recent key to the Oriental genera of Coenosiinae, Crosskey (1962) has included Pectiniseta, but he doubted whether it could be distinguished satisfactorily from Lispocephala and maintained as a good genus. In my opinion, not only Pectiniseta but also Parvisquama Malloch can be maintained as distinct genera, closely related to but distinct from Lispocephala. It is possible that new species of Lispocephala will be discovered with a long-plumose arista that will be indistinguishable from Pectiniseta in the female sex: in this case Pectiniseta might be used as a name for a subgeneric segregate within Lispocephala. Using the characters of the head and of the female ovipositor discussed below, I am continuing to treat Pectiniseta as a genus.

Genus Pectiniseta Stein Pectiniseta Stein, 1919: 96, 145. Type-species: Caricea prominens Stein, 1910 (= Coenosia pectinata Stein, 1900), by monotypy. Pectiniseta Stein; Malloch, 1928: 315; Malloch, 1929b: 163; Malloch, 1929c: 326; Seguy, 1937: 223,231,242; Emden, 1940: 97; Crosskey, 1962: 400; Snyder, 1965: 201, 218; Hennig, 1965: 65.

Diagnosis Pectiniseta can be distinguished from the other genera of the Coenosiinae by the long-pectinate arista of the male (fig. 1) and by the long-plumose arista of the female (fig. 2) combined with the presence of 2 ors and 1 p seta on mid tibia.

Description Head rather angular in male, with a long face and with antennae inserted high; less angular in female, with face shorter and less receding. Frons dichoptic in both sexes, at middle almost as broad as an eye. Interfrontalia with a large clearly defined frontal triangle which reaches lunula. Ocellar setae strong. Two pairs of reclinate ors. Male with third antennal segment long, just over four times as long as broad, pointed at anterior tip, in frontal view reaching epistoma; female with this segment shorter and normal, a little over three times as long as broad, not pointed at tip, but reaching epistoma. Male with arista pectinate, with a few tiny hairs on apical two-thirds below, but with long regular hairs on most of length above, the longest of which are about one-third length of third antennal segment; female with arista long-plumose, not pectinate except infulvithorax which is pectinate as in the male, the longest plumosity as long as length of third antennal segment. Male with face long and strongly receding, in lateral view face about one and a half times as long as frons (measured from vibrissa to profrons to anterior ocellus). Mentum of proboscis glossy. Dc 1 + 3, with a stronger setula before prst seta. Anterior ia strong. Three stpl setae, the lower one equidistant from the upper two and slightly weaker than anterior one. Scutellum with the apical and sub-basal lateral setae strong. Mid femur with o a and 1 p preapical seta. Mid tibia without submedian setae except for 1 p at basal two-fifths. Hind femur with 1 d preapical seta, in addition to the ad. Hind tibia with 2 ad and 2 pd setae. Lower squama projecting well beyond lower one. Sternite 1 bare. 143

In the genera Pectiniseta, Lispocephala and Parvisquama the aedeagus with its associated structures is very similar, but there is considerable diversity in the ovipositors. In Pectiniseta (figs 4-6), the ovipositor is short. Segment 6 has a normally developed tergite and sternite. Segments 7 and 8 are fused: tergite 7 + 8 extends right round the segment, like a ring, and is even fused ventrally, whilst sternite 7 + 8 has been displaced posteriorly and is divided longitudinally into two small plates. The apical sternite is normal, triangular in shape, the apical tergite is absent,· and the cerci are large. The spermathecae (fig. 7) are large. In species of Lispocephala dissected for comparison, the ovipositor is similarly short. Segments 7 and 8 are distinct and not fused. Segments 6 and 7 have the tergites extending right round the segments, ring-like, and fused ventrally, but unlike Pectiniseta they are divided dorsally along the mid-line; these segments have no sternites. Tergite 8 is present, and sternite 8 is present as a single plate though deeply cleft medially. The apical sternite is narrow and boomerang-shaped, the apical tergite is absent, and the cerci are small. The spermathecae are very large. Parvisquama ciliata Malloch has a longer slimmer ovipositor with small cerci and spermathecae. There is very little sclerotization: tergite 6 consists of a pair of longitudinal strut-like sclerites and sternite 6 is minute and round. Segments 7 and 8 are fused: tergite 7 + 8 is round with 2 anterior projections, sternite 7 + 8 is absent. The apical tergite is present but minute, and the apical sternite normal and oval.

Synonymy by Pont, 1970: IOO. In the above bibliography, the catalogue references of Stein (1919) and Seguy (1937) have been omitted. Although the holotype of pectinata has been destroyed, Stein's description fits the present species perfectly. In addition, it is the only species of the genus known from New Guinea. 145

The synonymy of peetinata and prominens was first suggested by Malloch (I 929b : 163), but this synonymy has been followed neither by Malloch himself (1929C) nor by other authors (Seguy, 1937; Snyder, 1965).

Stein described prominens from 2 males and 4 females collected on Socotra Island by Simony, which should be preserved in the Zoological Museum of the Humboldt­ University, Berlin. None of the original material could be located, and Dr Schumann wrote to me (letter of 19th August, 1969): "Die Art Pectiniseta prominens konnte ich ebenfalls in unserer Sammlung nicht finden. Hinter dem Etikett sind zwar Einstiche von Nadeln zu entdecken, jedoch fehlen jegliche Fliegen."

6'. Head: Ground-colour black. Parafrontalia, frontal triangle and occiput densely grey to yellowish-grey pruinose; parafacialia, face and genae lighter grey pruinose. Interfrontalia black, matt from almost all points of view. Eyes bare. Frons broadening uniformly from vertex to lunula. Vertical setae strong; pvt short, fine. Post-ocular setulae short, uniform, with scattered setulae below the upper row. Two pairs of inclinate ori, the lower one strongest, without interstitials; upper ors strongest and closer to the lower one than to vertical; parafrontalia with 3-5 short setulae outside ori, otherwise bare. Parafrontalia moderate, at middle of frons a parafrontale equal to twice diameter of anterior ocellus and one-third width of interfrontalia at this point. First and second antennal segments dark, second yellow at tip; third segment orange-yellow to brownish. Parafacialia linear almost throughout, mostly hidden by the eye in profile. In lateral view, vibrissa I angle well behind level of profrons. Genae very slender; the depth below lowest eye-margin well under half width of third antennal segment. Vibrissae long and strong; peristomal setae quite long and sparse. Mentum of proboscis dark brown. Palpi slim, yellow, brown at base.

Thorax: Ground-colour black. Mesonotum grey to yellowish-grey dusted, usually with weak traces of 3 brown vittae, a median (aer) one and a pair of paramedian (de) ones; the median one sometimes very distinct, sometimes all three very distinct. Pleura and scutellum dusted as mesonotum, the latter dark on sides. Anterior spiracle yellowish to brownish. Aer in 2 rows before suture, in 3-4 rows behind. Inner h short, half or less than half as long as outer one. Posterior ph one-third longer than anterior one. Two propleural and 2 prostigmatal setae, without ground-setulae. Disc of scutellum often bare on basal third, with up to 15 setulae.

Legs: Trochanters, knees, tibiae and tarsi yellow; coxae and femora dark brown, the coxae sometimes partially pale. Fore femur with a row of about 6 pv setae, of uniform length and strength. Fore tibia without submedian setae. Mid femur without av setae, with a few short pv in basal half; I a at basal two-fifths. Hind femur with I pv seta just before middle, and sometimes with a few more short pv, and 3-4 moderate sparsely placed av setae; ad row complete. Hind tibia with 2 short pd, at basal fifth and at middle; 2 ad opposite them, the apical one strongest; I short av, just beyond middle.

Wings: Virtually clear, the veins yellow. Epaulet brownish, basicosta yellow to brown. Costal spine inconspicuous. Small cross-vein below or slightly apicad of the point where vein I enters costa, at or just beyond middle of discal cell. Hind cross-vein straight, upright, slightly longer to slightly shorter than the apical section of vein 5. Veins 3 and 4 subparallel towards wing-margin. Squamae white, halteres yellow. 146

Abdomen: Short, cylindrical Tergite 1 + 2 and the sides of tergite 3 yellow, tergites 3 and 4 with pale incisures; otherwise dark. In posterior view, tergites 3-5 and the genital tergites densely grey dusted, tergite 1 + 2 appearing undusted except on posterior margin. Tergites 3-5 with black undusted paramedian spots, those on tergites 3 and 4 large and separated by a black undusted median vitta, those on tergite 5 small and confined to anterior half of tergite; sometimes those on tergite 5 also large and separated by a median vitta, and tergite 1 + 2 with a dark median spot. Sides of tergites dusted, except for the pale parts, tergites 3 and 4 with broad dark­ brown undusted spots. Genital segments without spots. Tergites 3-5 each with a strong lateral discal seta, placed just outside or on the edge of the black spots, otherwise without well-developed setae except for (usually) a strongish pair of paramedian marginals on tergite 4. Measurements: Length of body, 3.0-3.5 mm. Length of wing, 2.5-3.0 mm.

~. Differs from the male as follows. Head: Differences as given in the generic description. Legs: Femora pale basally in two specimens. Mid femur with the pv setae longer. Hind femur usually with 2 long pv setae and with up to 5 short av. Hind tibia with the ad setae longer and stronger, and the pd either longer or shorter. Abdomen: Short and pointed, not cylindrical. Markings as in male, but spots on tergites 3 and 4 rather smaller. Tergite 1 + 2 with some dust posteriorly. Setae as in male, but rather weaker, the laterals on tergite 3 usually absent. Measure­ ments: Length of body, 3.5-4.0 mm. Length of wing, 3.0-3.5 mm. In this species, the cercal plate of the male hypopygium (fig. 27) is most like that of societas and torresiana." it is broader and more densely bristled than in occuita, australis and similis. The male 5th sternite is unlike that of any other species except for australis and torresiana in that it is entirely haired and without setae. The shape, in profile, although slightly variable (figs 10-12), is also consistently different in ground-plan from the other species except for torresiana: after the median ventral notch, the sternite is directed slightly ventrad again before running out to the tip. There is some slight geographic variation in shape and in distribution of the ground-hairs. But it should be borne in mind that many of the hairs are on the internal face of the sternite, and so any difference in the angle of inclination of the sternite during observation will produce apparent differences in structure and ciliation. Thus fig. 21a is of a sternite rather ft.attened beneath a cover-slip and fig. 21 is of a sternite floating in creosote. Despite the similarities in genital structure between this species and torresiana, pectinata can be distinguished immediately by the dark-brown femora.

~. Differs from the male as follows: Head: Differences as given in the generic description. Thorax: Rather more distinct traces of brownish vittae present, a median (acT) one and a pair of paramedian (dc) ones. Legs: Mid and hind femora often rather infuscated in apical quarter to third. Fore femurwith the pv row developed normally, the setae uniform; several long pv setulae among the setae in basal half or more. Mid femur with 3-4 short pv setae in basal third. Hind femur with 2 strong pv setae around middle. Hind tibia with the ad setae much longer and stronger. Abdomen: Short and pointed, not cylindrical. Tergites 3 and 4 not very yellow at sides, tergite 5 pale at tip. Markings as in male, but spots on tergite 5 larger and separated by a dark median vitta. Setae as in male, but tergite 5 with neither lateral discals nor median marginals. Measurements: Length of body, 3.0-3.5 mm. Length of wing, 2.5-3.0 mm.

P. similis can be recognized by the external characters without difficulty. The male 5th sternite is very characteristic: the apical part is greatly elongated and curved, and is longer than in any of the other species. It is covered with more numerous and longer setulae than in any other species. For further discussion, see under occulta novo 149

The cereal plate of the male genitalia (fig. 30) is most like that of occulta and australis: it is narrower and more sparsely bristled than in pectinata, societas and torresiana. However, it is more bulbous in the basal part than is occulta.

Length of wing, 2.5-3.0 mm. The cercal plate of the male genitalia (fig. 28) is most like that of australis and similis: it is narrower and more sparsely bristled than in pectinata, societas and torresiana. It is, however, less markedly swollen in the basal part than are australis and similis. . The male 5th sternite is very similar to that of similis, and these two species are more closely related to each other than to the other four Australasian species. The bristling of the sternite is rather similar in the two species, with long setae along the whole length of the apical part: as the apical part is mHch shorter in occulta than in similis, there are fewer setae in that species than in similis.

It is, however, more bulbous in the basal part than is occulta. The male 5th sternite is rather short and simple, unlike that of any species in the genus. The apical part is without any notch or indentation in either dorsal or lateral view, and is covered with only fine setulae few, if any, of which are longer than that part of the sternite on which they are situated.

Measurements: Length of body, 3.0 mm. Length of wing, 2.5 mm. The cercal plate of the male genitalia (fig. 32) is most like that of societas and pectinata,' it is broader and more densely bristled than in the other species, but is, if anything, rather broader but less densely bristled than in either societas or pectinata. The male 5th sternite is most like that of pectinata, and in lateral view the similarity is most striking (cf. figs 10-12 and 16). Like this species and australis, torresiana lacks all strong setae but, unlike australis, it possesses a preapical indentation in lateral view. In spite of the similarities in genital structure between torresiana and pectinata, the entirely yellow femora, except for the partially darkened femora of the female, will separate it immediately from pectinata.

Pectiniseta societas Malloch (Figs 13, 23, 29)

Pectiniseta societas Malloch, 1929c: 326, fig. I. Holotype 6', TAHITI. In the British Museum (Natural History), London [revid. Lee, Crust and Sabrosky, 1956: 335; examined by myself]. Pectiniseta societas Malloch; Seguy, 1937: 231. Of this species I have studied only that part of the type-series present in the BMNH. This consists of the holotype 6', allotype , and I I para types. . Lee, Crust and Sabrosky (l.c.) list the holotype and 12 paratypes as being in the BMNH. Three paratypes, I collected by Cheesman and 2 by Tonnoir, are not in the BMNH and were not located by Lee, Crust and Sabrosky. P. societas is very similar to pectinata. It has a dark thorax and dark femora, the upper ori is strong and well-developed, and the male has the setae of the pv row on fore femur of uniform length and strength. In the male, the 5th sternite is very characteristic (see below). There is some variation, particularly in the female sex. The mesonotum may have more extensive dark markings; the long femoral setae may be more robust; the abdomen is sometimes very dark. The female is indistinguishable from that of pectinata. The cercal plate of the male genitalia (fig. 29) is most like that of pectinata and torresiana: it is broader and more densely bristled than in occulta, australis and similis. The male 5th sternite is unique and striking, but clearly closer to that of occulta and similis than to pectinata,and torresiana, both in shape and setation. It is distinguished above all by the absence of setae except for the tuft on the inner apical edge. The ground-setulae, too, are almost totally absent, and none are visible when the sternite is viewed in profile. Material examined.-Society Islands: Tahiti, no further locality, 19.vii.1925 (6' holotype, Sj2 allotype and I Sj2 paratype, BMNH) and IO.iii. 1925 (I 6' and I Sj2 paratypes, BMNH), L. E.

Pectiniseta fulvithorax Malloch Pectiniseta fulvithorax Malloch, 1929b: 163. Holotype , SAMOA: Savaii, Safune. In the B. P. Bishop Museum, Honolulu [revid. Lee, Crust and Sabrosky, 1956: 3 I 8; not examined by me]. Pectinisetafulvithorax Malloch; Seguy, 1937: 231. I have seen only one specimen of this species, Malloch's male allotype, which is in the BMNH. The abdomen is missing, as was noted by Malloch, and all the legs are missing, too. This is a very characteristic species that may be easily recognized by the entirely pale colour of the thorax. The other characters given in the key, taken from the single specimen studied, may prove useful additional diagnostic characters.
